The defensive experiment: 2.Qe1 Ne5 3.Rf4 Very difficult to judge - probably better for black. b.) The endgame experiment: 2.Qf3 Ne5 3.Bxc3 Qxe4 4.Bxe5 Qxe5 Looks won for Black. As 1.Qf1 Nxe4 is won for White I agree that 1.Qf1 is better than 1.Qf2. But the major quality of Ng4 doesn't seem to be the tempo here anyway but the much better square for the knight,so how about 1.Qf1 Ng4 I wasn't able to find anything leading to a major advantage for White - looks pretty even - I can't look at "60 memorable games" - is this line covered? I don't think it is a really good testposition - the programs get Qf1 sooner or later but not for the right reason ( look at Yace's eval - just like Fritz). Regards, pete
